Leclerc attempted to solo Torre Egger on 10 September 2016 but after a bivouac circa four pitches below the summit, the Squamish based alpinist was forced to retreat the next morning due to snowfall. According to details published on Patagonia Vertical, Leclerc returned up the valley and bivied in the Niponino camp on Thursday night, while on Friday he moved his camp to the glacier below the east face of the mountain.

Setting off at 2:45am on Saturday, Leclerc climbed circa 300m of new terrain to the right of the line chosen in 1980 by the Italians Bruno De Donà and Giuliano Giongo before following the line of his previous attempt, namely the "Winter link-up" line that leads to Titanic at half height. This involved climbing below a threatening serac - his first time ever - and a long mixed pitch (M5 A1), while on the headwall he soloed the majority of the climbing. He changed into rock shoes for some sections and back into boots and crampons higher up, resorting to aid where necessary. He summited at 6pm and after down climbing the first pitch abseiled off the edge of the headwall using Abalakov v-threads. This direct descent enabled him to return to the safety of his tent at 23:00, 21 hours after having set off.
